As a part of our continuing studies on the organic selenium chemistry, we reported that ureas can be synthesized by the reaction of carbon monoxide with ammonia or amines in the presence of selenium catalyst and oxygen. 1,2) The formation of ureas in such cases was interpreted as involving the react
